DESCRIPTION

58V, 2A Step-Down

µModule Regulator

cromodule) converter. Included in the package are the

switching controller, power switches, inductor and all

support components. Operating over an input voltage

range of 3.6V to 58V, the LTM8050 supports an output

voltage range of 0.8V to 24V and a switching frequency

range of 100kHz to 2.4MHz, each set by a single resistor.

Only the bulk input and output filter capacitors are needed

to finish the design.

The LTM8050 is packaged in a 9mm × 15mm × 4.92mm

ball grid array (BGA) package suitable for automated

assembly by standard surface mount equipment. The

LTM8050 is available with SnPb (BGA) or RoHS compli-

ant terminal finish.
